A beginner — Why am I not able to convert to minutes?

minutes = input("Enter number of minutes you want to convert to seconds: ")
print (minutes + " minutes is " + float(minutes) * 60 + " seconds.")

I'm getting this error can only concatenate str (not "float") to str. But if I use str (instead of float), it just prints the number of minutes inputted 10 times eg 10101010....

Although many answers have been added, but there is one more way other than those and as simple as all others, maybe even simpler. Just separate your different data-types with a ,:)

print (minutes , "minutes is" , float(minutes) * 60 , "seconds.")

The reason this doesn't work is that float(minutes) * 60 returns a float, which cannot be concatenated to a string. However, str(minutes) * 60 will multiply the STRING minutes by 60, which is also not what you want.

The solution is to convert to float to perform the calculation, then convert back to a string. See the code below:

minutes = input("Enter number of minutes you want to convert to seconds: ")
print (minutes + " minutes is " + str(float(minutes) * 60) + " seconds.")

If you input 3, this code will print 3 minutes is 180.0 seconds.

Other ways of doing the same thing include:

Format strings:

print("%s is %0.1f seconds." % (minutes, float(minutes) * 60))

If you're using Python 3, f-strings:

print(f"{minutes} is {float(minutes) * 60} seconds.")

You cannot concatenate string with a float Use a format string instead:

print("%s minutes is %f seconds" % (minutes, float(minutes) * 60))
10 minutes is 60.000000 seconds

float(minutes) * 60 is not a string and therefore cannot be concatenated with with the rest of your string

consider converting float(minutes) * 60 to a string

minutes = input("Enter number of minutes you want to convert to seconds: ")
print (minutes + " minutes is " + str(float(minutes) * 60) + " seconds.")
