Minimum field width with strings – ANSWER – print(‘Student name (%5s)’ % ‘Bob’
the 5 specifies that there are a minimum of 5 characters and thus the print out would be
( Bob)
Conversion flags – ANSWER – alter the output of conversion specifiers
%08d adds leading zeros to the minimum width of 8 characters
precision components(Rounding) – ANSWER – Indicates how many digits to the right of
the decimal should be included
‘%.1f’ % 1.725 indicates a precision of 1 resulting in 1.7
.replace() – ANSWER – replace(old,new,count)
count replaces only the first occurrence
count can be left out
translation = translation.replace(‘one’, ‘uno’)
.find(x) – ANSWER – Returns the position of the first occurrence of item x in the string
if my_str is ‘Boo Hoo!’
my_str.find(‘!’) Returns 7
my-str.find(‘Boo’) Returns 0
my_str.find(‘oo’) returns 1
find(x, start) – ANSWER – Same as find(x) but begins the search at position start
find(x, start, end) – ANSWER – Same as find(x,start) but stops the search at position end
rfind(x) – ANSWER – Same as find but searches the string in reverse, returning the last
occurrence in the string
count(x) – ANSWER – Returns the number of times x occurs in the string
using in operator to check if a character or substring is contained in the string –
ANSWER – if ‘b’ in my_string
Comparing Strings – ANSWER – may be compared using relational operators (<> <=
etc..)
equality operators (==,!=)
1 \/ 2
membership operators (in,not in)
identity operators (is, is not)
my_str = ‘Hello’
my_str == ‘Hello” evaluates to True
relational comparison will compare the ASCII unicode values. if a string is shorter with
all the same characters then the shorter is considered less than
Do not use identity operators where you should be using an equality operator
comparisons are case sensitive
isalnum() – ANSWER – Returns True if all characters int he string are lowercase or
uppercase letters, or the numbers 0-9
isdigit() – ANSWER – Returns True if all characters are the numbers 0-9
islower() – ANSWER – Returns True if all characters are lowercase letters
isupper() – ANSWER – Returns True if all characters are uppercase letters
isspace() – ANSWER – Returns True if all characters are whitespace
startswith(x) – ANSWER – Returns True if the string starts with x
endswith(x) – ANSWER – Returns True if the string ends with x
capitalize() – ANSWER – Returns a copy of the string with the first character capitalized
and rest lowercased
lower() – ANSWER – Returns a copy of the string with all characters lowercased
upper() – ANSWER – Returns a copy of the string with all characters uppercased
strip() – ANSWER – Returns a copy of the string with leading and trailing whitespace
removed
can be used to turn a string literal into a list of items by using the whitespace character
as the default separator
if it was strip(\/) the default separator would be the \/ character. If the string contained a
double \/\/ then an empty list element would be created
title() – ANSWER – Returns a copy of the string with the first letters of words capitalized<\/p>\n","protected":false},"excerpt":{"rendered":"
