# 7 Daily Use Python String Functions

Here are seven Python string manipulation methods (functions). Those are Find, Join, Validation, Change case, Split, Replace, and Strip. Note: In Python, there is no CHAR data type. So only strings you need to use.

## Python string functions

Here are the list of Python string functions demonstrated with examples.

### 1. Python string find

Neat function to find specific string if it is present or not.

```
text = 'This is text'
nums = '123456'

# finding text
a= text.find('is')           
b= text.find('your') 
print(a)  
print(b)
```

Output

```
2 
-1 

** Process exited - Return Code: 0 **
```

### 2. Python validate a string

Helpful to do [validation checks](https://cs.stanford.edu/people/nick/py/python-string.html)on the strings.

```
text = 'This is text'
nums = '123456'
# Validation checks       
print(text.isalpha())           
print(text.isdigit())            
print(nums.isdigit())
```

Output

```
False 
False 
True 

** Process exited - Return Code: 0 **
```

### 3. Python string concatenation

Useful to concatenate strings with or without separator.

```
text = 'This is text'
nums = '123456'
a=''.join((text,nums)) 
b=' '.join((text,nums)) 
print(a)
print(b)
```

Output

```
This is text123456 
This is text 123456 


** Process exited - Return Code: 0 **
```

### 4. Python change case of a string

Useful to convert case of the string.

```
text = 'This is text'
# case changing           
print(text.upper())             
print(text.lower())
```

Output

```
THIS IS TEXT 
this is text 

** Process exited - Return Code: 0 **
```

### 5. Python string split

Effective to Split string into words.

```
# splitting string
text = 'This is text'
a=text.split(' ')
print(a)
```

Output

```
['This', 'is', 'text'] 

** Process exited - Return Code: 0 **
```

### 6. Python replace string

Handy method to replace part of the string with the other one.

```
text = 'This is text'
# substitution
a=text.replace('is','was')
print(a)
```

Output

```
Thiswas text 

** Process exited - Return Code: 0 **
```

### 7. Python stripe string

Advantageous to remove space in trailing and leading edges and both.

```
text1 = 'This is text '
a=text1.rstrip()             # remove trailing space

text2 = ' This is text'
b=text2.lstrip()             # remove leading space

text3 = ' This is text '
c=text3.strip()              # remove trailing and leading spaces

print(a)
print(b)
print(c)
```

Output

```
This is text 
This is text 
This is text 

** Process exited - Return Code: 0 **
```
