By using floating-point number and string to explain the format printing method of ptint() function, we can print the information we need on the console at will in the development process.
The first is the format printing method of the decimal point in the console.
Format the decimal point by%. 3F
Print ("%. 3F"% 3.1415926) # keep 3 decimal places
Print ("%. 2F"% 3.1415926) # keep 2 decimal placesFormat the decimal point by {:. 3F}
Print ("{:. 3F}". Format (3.1415926)) # keep 3 decimal places
Print ("{:. 2F}". Format (3.1415926)) # keep 2 decimal placesEnsure the formatting of decimal points through the round() function
Print (round (3.1415926, 3)) # retains 3 decimal placesNext is the string formatting method.
Initialize a and B strings for string formatting
A = 'the result of a is:'
b = 10Format using%
print(" %s%d " % (a, b))Use the format () function to format. A and B are formatted in order by default
print("{}{}".format(a,b))Format with format() function and format with ‘{0} {1}’ placeholder
print("{0}{1}".format(a,b))Format with format() function and format with ‘{a} {B}’ parameter value placeholder
print("{a}{b}".format(a=a,b=b))“>” use right alignment
Print ('name: {0:>5} \ ntype: {1:>5}'.format ('official account ',' Python concentration camp '))”
Print ('name: {0:<5} \ ntype: {1:<5}'.format ('official account ',' Python concentration camp '))Format using f ‘{}’, which supports Python 3 Version above 6
Print (the result of f'a is: {a} the result of B is: {B} ')Join [Python concentration camp] to get more benefits!
