It returns true if all the characters of the string(if exists) is true otherwise it returns false. A title string is the one in which the first character is upper-case whereas the other characters are lower-case.

It returns true if the string is titled properly and false otherwise. It returns true if the characters of a string are white-space, otherwise false. It returns false if characters of a string are in Upper case, otherwise False. It returns true if all the characters of s are printable or s is empty, false otherwise. It returns true if the string contains only numeric characters. It returns true if the characters of a string are in lower case, otherwise false.

It returns true if the string is the valid identifier. It returns true if all the characters are digits and there is at least one character, otherwise False. It returns true if all the characters of the string are decimals. It returns true if all the characters are alphabets and there is at least one character, otherwise False. It returns true if the characters in the string are alphanumeric i.e., alphabets or numbers and there is at least 1 character.

It throws an exception if string is not found. It returns a formatted version of S, using the passed value. It returns the index value of the string where substring is found between begin index and end index. It defines tabs in string to multiple spaces. It returns a Boolean value if the string terminates with given suffix between begin and end. Default encoding is 'utf-8'.Įndswith(suffix ,begin=0,end=len(string)) It counts the number of occurrences of a substring in a String between begin and end index.ĭecode(encoding = 'UTF8', errors = 'strict')ĭecodes the string using codec registered for encoding.Įncode S using the codec registered for encoding. It returns a space padded string with the original string centred with equal number of left and right spaces. It returns a version of s suitable for case-less comparisons. It capitalizes the first character of the String. Python provides various in-built functions that are used for string handling. Here is the simple example of escape sequence. Print('Hello World!') Output: Hello World! Print('Hello World') Output: Hello World Python3') Output: Python1 Python2 Python3 The list of an escape sequence is given below: Sr. We will discuss how formatting is done in python.Ĭonsider the following example to understand the real use of Python operators. It makes use of the format specifiers used in C programming like %d or %f to map their values in python. To define any string as a raw string, the character r or R is followed by the string. Raw strings are used in the cases where we need to print the actual meaning of escape characters such as 'C://python'. It returns true if a particular substring is not present in the specified string.

It is also a membership operator and does the exact reverse of in. It returns if a particular sub-string is present in the specified string. It is used to access the characters from the specified range. It is used to access the sub-strings of a particular string. It concatenates the multiple copies of the same string. It is known as concatenation operator used to join the strings given either side of the operator.
