Python and PyQt string can't print

Question

So, I'm using Python with PyQt and I have a very strange problem. A string that prints OK at one point doesn't print OK after a few lines of code! Here's my code:

name = str(self.lineEdit.text().toUtf8())
        self.let_change = Search()
        name_no_ind = self.let_change.indentation(name)
        print(name_no_ind)
        name_cap = self.let_change.capital(name)
        name_low = self.let_change.lower(name)
        print(name_no_ind, name_cap, name_low)
        col = self.combobox.currentIndex()
        row = 0
        for i in range(0, self.tableWidget.rowCount()):
            try:
                find_no_ind = self.let_change.indentation(self.tableWidget.item(row, col).text())
                find_cap = self.let_change.capital(self.tableWidget.item(row, col).text())
                find_lower = self.let_change.lower(self.tableWidget.item(row, col).text())
                if name_no_ind or name_cap or name_low in find_no_ind or find_cap or find_lower:
                    self.tableWidget.setItemSelected(self.tableWidget.item(row, col), True)
                    print("Item found in %d, %d" % (row,col))
                row += 1
            except AttributeError:
                row += 1 

And here's what I get:

Αντωνης
('\xce\x91\xce\xbd\xcf\x84\xcf\x89\xce\xbd\xce\xb7\xcf\x82', '\xce\x91\xce\x9d\xce\xa4\xcf\x8e\xce\x9d\xce\x97\xce\xa3', '\xce\xb1\xce\xbd\xcf\x84\xcf\x8e\xce\xbd\xce\xb7\xcf\x82')
Item found in 0, 0

Isn't that strange? It prints OK and then it doesn't. Does anybody know what can I do?

P.S.: Here are the functions:

# -*- coding: utf-8 -*-
class Search():
    #A function that removes indentations: 
    def indentation(self, name):
        a = name
        b = ["ά", "Ά", "ή", "Ή", "ώ", "Ώ", "έ", "Έ", "ύ", "Ύ", "ί", "Ί", "ό", "Ό"] 
        c = ['α', 'Α', 'η', 'Η', 'ω', 'Ω', 'ε', 'Ε', 'υ', 'Υ', 'ι', 'Ι', 'ο', 'Ο']
        for i in b:
            a = a.replace(i, c[b.index(i)])
        return a

    # A function that makes letters capital:    
    def capital(self, name):
        a = name
        greek_small = ["α", "β", "γ", "δ", "ε", "ζ", "η", "θ", "ι", "κ", "λ", "μ", "ν", "ξ", "ο", "π", "ρ", "σ", "τ", "υ", "φ", "χ", "ψ", "ω", "ς"]
        greek_capital = ["Α", "Β", "Γ", "Δ", "Ε", "Ζ", "Η", "Θ", "Ι", "Κ", "Λ", "Μ", "Ν", "Ξ", "Ο", "Π", "Ρ", "Σ", "Τ", "Υ", "Φ", "Χ", "Ψ", "Ω", "Σ"]
        for i in greek_small:
            a = a.replace(i, greek_capital[greek_small.index(i)])
        return a
    #A function that makes letters lower:    
    def lower(self, name):
        a = name
        greek_small = ["α", "β", "γ", "δ", "ε", "ζ", "η", "θ", "ι", "κ", "λ", "μ", "ν", "ξ", "ο", "π", "ρ", "σ", "τ", "υ", "φ", "χ", "ψ", "ω", "ς"]
        greek_capital = ["Α", "Β", "Γ", "Δ", "Ε", "Ζ", "Η", "Θ", "Ι", "Κ", "Λ", "Μ", "Ν", "Ξ", "Ο", "Π", "Ρ", "Σ", "Τ", "Υ", "Φ", "Χ", "Ψ", "Ω", "Σ"]
        for i in greek_capital:
            a = a.replace(i, greek_small[greek_capital.index(i)])
        return a

Basically, it capitalizes or lowers Greek characters...

SOLUTION!!!: Steve solved the initial problem and based on what he said, I came up with this that solves everything:

name = str(self.lineEdit.text().toUtf8())
        self.let_change = Search()
        name_no_ind = self.let_change.indentation(name)
        name_cap = self.let_change.capital(name)
        name_low = self.let_change.lower(name)
        name_list = [name, name_no_ind, name_cap, name_low]
        col = self.combobox.currentIndex()
        row = 0
        for i in range(0, self.tableWidget.rowCount()):
            try:
                item_ = str(self.tableWidget.item(row, col).text().toUtf8()) 
                find_no_ind = self.let_change.indentation(item_)
                find_cap = self.let_change.capital(item_)
                find_lower = self.let_change.lower(item_)
                item_list = [find_no_ind, find_cap, find_lower]
                for x in name_list:
                    for y in item_list:
                        if x in y:
                            self.tableWidget.setItemSelected(self.tableWidget.item(row, col), True)
                row += 1
            except AttributeError:
                row += 1

I would say that one r both of self.let_change.capital(name) or self.let_change.lower(name) is overwriting it by using the name of the input parameter or possibly changing the encoding. Since you have not posted the code for them I can not be sure.

Sorry, they are not the problem. The problem is that you are printing them differently:

>>> print(capital(name))
ΑΝΤΩΝΗΣ
>>> print(capital(name), name)
('\xce\x91\xce\x9d\xce\xa4\xce\xa9\xce\x9d\xce\x97\xce\xa3', '\xce\x91\xce\xbd\xcf\x84\xcf\x89\xce\xbd\xce\xb7\xcf\x82')
>>> print(capital(name))
ΑΝΤΩΝΗΣ
>>> print(name, name)
('\xce\x91\xce\xbd\xcf\x84\xcf\x89\xce\xbd\xce\xb7\xcf\x82', '\xce\x91\xce\xbd\xcf\x84\xcf\x89\xce\xbd\xce\xb7\xcf\x82')
>>> print(name,)
('\xce\x91\xce\xbd\xcf\x84\xcf\x89\xce\xbd\xce\xb7\xcf\x82',)
>>> print(name)
Αντωνης
>>> print("%s = %s" % (name, capital(name)))
Αντωνης = ΑΝΤΩΝΗΣ
>>> 

So you either need separate print statements or the use of a format string.
